Platform dependency

We aim to make as many APLTree sub-projects available for all platforms Dyalog is officially supporting except AIX. This is a major project but it was eased by the fact that Dyalog introduced system functions into version 15.0 that make the job much easier.

However, since we also tried to make sure that every APLTree project runs at least with the oldest supported version of Dyalog (14.0 at the time of writing) we had a dilemma here: we need 15.0 for a platform independent strategy.

Therefore it was decided to make a split: what is the current version of any APLTree project is available from http://download.aplwiki.com/Prior15.0. Naturally these versions are no longer actively supported, although we will continue to fix serious bugs for quite a while.

On http://download.aplwiki.com we will provide only versions of the APLTree project that are either truly platform independent or are bound to a particular platform by definition; examples are WinSys and ShowChmHelp.
